Description
Bimetallic and Fe-Ni-Mo Trimetallic Heterogeneous Catalysts
Global warming has become an issue concerning the emission of CO2
which is a greenhouse gas. Methane is a major component of natural gas
which is inexpensive and very attainable. Combining CO2 and CH4 in a
single process to produce value added chemicals is very desirable. The
primary objective of this study is to develop novel iron based catalysts to
enhance the reaction of CO2 with CH4. The heterogeneous Fe-based bimetallic
and trimetallic catalysts were synthesized via a wet incipient impregnation
method to uniformly coat the metal salts to the pre-treated support
(SiC, SiO2 and ZrO2). The catalyst was dried in the oven at 80 degrees C for two
hours before subjected to the furnace to calcine at 450 degrees C for five hours. The
synthesized catalysts are to be tested for CO2 dry reforming with methane
through a flow bed reactor with controlled CO2 and CH4 flow rate and online
GC analysis to determine the catalyst performance such as selectivity,
conversion and stability. Catalyst characterization such as Brunauer Emmett
Teller (BET) surface area, pore size and volume, Transmission Electron
Microscope (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction
(XRD), and CO Chemisorption and Temperature Programed Reaction (TPR)
will be carried out at Brookhaven National Laboratory with an aim to establish
relationships between activity and properties. The fundamental study
will serve as great guidance for us to understand the reaction pathway of dry
reforming of CO2 with CH4.
